once in awhile i would use earphones with my PB - but it only came out on one side unless i played around with it and got the jack it in the right spot. i never thought it was a problem with my PB, but rather the earphones. well, recently i plugged it into my new speakers, but only one side was playing sound! i then tried my friends earphones - same result. then my friends speakers - same thing. does anyone know if there is a way to fix this problem?
